Change Table Prefix = Broken site

  • When I tried changing the default wp table prefix, nothing seemed to happen. It just loaded a blank screen.

    Now, the entire site is like that. When I try to load the site, it loads for about 25 seconds and then shows nothing. Completely blank. Even the source is completely blank.

    I figured that changing the prefix conflicted with a theme or plugin component, so I went into phpmyadmin to change it back. But, the prefix was still set to the default “wp_”.

    I manually backed up the .htaccess in the root directory before doing anything. I tried putting it back but it doesn’t help.

    Any idea how to figure out what is wrong? Thanks.

  • Same here.

    Hello, is the change in the wpconfig $ table_prefix = ‘mynewprefix_’; changed?

    I had s similar problem, i got to see the first screen of a WordPress installation after changing this setting.

    When i put the wp-config.php file permission to 777 when i made the change, everything seemed to go without any problems. Don’t forget to change it back 644 after you’re done ??

    Maybe it also prevents your problem next time.

    @brummbaer I’m not that into Mysql, I only knew how to delete unwanted entries.
    But there are tables which got the wp_ in front of the actual prefix. In my case it’s like wp_schwarzgraupostmeta. They only contain some stuff like the first hello-world post.
    And then there are tables with a random-prefix containing my real posts. But how do I tell wordpress to use these tables? if I change the prefix in the wp_config.php and try to access the admin it just do a fresh 5-minute-install.

    got it! I just needed to ad an underscore after the random-prefix in my wp_config.php.
    Thank you irriterik and Brummbaer.
